Are the Black Lion Chest seasonal? I just recently returned to the game after being away since 2013. I never really cared about the Black Lion Chest, until I saw the jade tech jet pack. I would love to get this item. However my question is, I noticed from this video (Posted Below) that all his chest were Green, and he got the item after several tries. All the chest I've opened have been red. Did I just waste my money on buying keys with zero chance of getting the item I want? And if so, do these items ever come back around so I can have a chance at getting them again sometime in the future? I'm just trying to figure out how this system works. Any help would be much appreciated. Thanks in advance...
